Which integrations are available for this server?

Enables monitoring of Chainlink price feeds on the BNB Chain to detect oracle staleness, stablecoin depegs, and market anomalies. Provides real-time cross-chain oracle monitoring, anomaly detection, and risk intelligence by reading data feeds across multiple EVM networks. Enables monitoring of Chainlink price feeds on the Ethereum network to detect oracle staleness, stablecoin depegs, and market anomalies. Enables monitoring of Chainlink price feeds on the Polygon network to detect oracle staleness, stablecoin depegs, and market anomalies.

Chainlink Sentinel

AI-powered cross-chain risk monitor using Chainlink Data Feeds. Reads on-chain oracle data across 6 EVM chains, detects anomalies in real-time, and generates actionable risk intelligence — all as MCP tools for AI agents.

What it does

Cross-chain oracle scanning: Reads 30+ Chainlink price feeds across Ethereum, Polygon, Arbitrum, Base, Avalanche, and BNB Chain
Anomaly detection: Identifies stale oracles, stablecoin depegs, cross-chain price deviations, and potential oracle attacks
Risk reports: Generates comprehensive risk assessments with severity scoring, chain health metrics, and recommendations
Zero config: No API keys needed. Uses Chainlink's on-chain data via public RPCs

Built with Chainlink

Chainlink Product	Usage
Data Feeds	Primary data source — reads AggregatorV3Interface across all chains
CRE	Cross-chain runtime for multi-chain oracle monitoring
CCIP	Cross-chain message passing for alert propagation (planned)

MCP Tools (6)

Tool	Description
`sentinel_scan`	Full cross-chain scan — all feeds, all chains, all anomalies
`sentinel_chain`	Scan a specific chain (ethereum, polygon, arbitrum, etc.)
`sentinel_feed`	Read a single Chainlink price feed
`sentinel_stablecoins`	Monitor USDC/USDT/DAI pegs across all chains
`sentinel_risk_report`	Generate AI risk report with recommendations
`sentinel_compare`	Compare a price pair across chains (detect deviations)

Quick Start

# Install
npm install

# Build
npm run build

# Run as MCP server
npm start

Use with Claude Code

Add to ~/.claude/claude_desktop_config.json:

{
  "mcpServers": {
    "chainlink-sentinel": {
      "command": "node",
      "args": ["/path/to/chainlink-sentinel/dist/index.js"]
    }
  }
}

Then ask Claude: "Run a cross-chain sentinel scan" or "Check stablecoin pegs"

Anomaly Types

Type	Severity Logic	Description
Stale Oracle	>1h major, >2h minor	Oracle hasn't updated within expected heartbeat
Depeg	>0.5% warning, >5% critical	Stablecoin deviating from $1.00 peg
Cross-chain Deviation	>2% medium, >10% critical	Same pair showing different prices on different chains
Flash Crash	Price drop >20% in 1 round	Sudden price movement suggesting manipulation

Feeds Supported (30+)

BTC/USD, ETH/USD, SOL/USD, LINK/USD, USDC/USD, USDT/USD, DAI/USD, AAVE/USD, UNI/USD, MATIC/USD, ARB/USD, AVAX/USD, BNB/USD — across 6 chains.

Convergence Hackathon

Track: CRE & AI / Risk & Compliance

Why Chainlink Sentinel matters:

DeFi protocols need real-time oracle health monitoring
Cross-chain deviations signal arbitrage or attacks
Stablecoin depeg detection prevents cascading liquidations
AI agents can autonomously act on risk intelligence

Differentiation:

First MCP-native Chainlink monitoring tool
Works with any AI agent (Claude, Cursor, Windsurf)
Zero API keys — reads directly from on-chain Chainlink contracts
Cross-chain by default — not single-chain monitoring
